BAG-DUSTING' MACHINE.

Application filed October 14=,'1920.' SerialNo. 417,026,

T 0 all whom it may concern:

Be it known that I, CARMINE TAL TTA, a

subject of the King of Italy, residing at Cementon, in the county of Lehigh and State of Pennsylvania, have invented certain new and useful Improvementsin Bag- Dusting Machines, of which the following is a specification. I v c The invention relates to improvements in bag dusting machinesfifl It has heretofore generally been'the practice toprovide' a bag dnsting machine consisting of a suitable wheel composed of openwork formation receiving bags, which, upon a rotation of the drum, are dusted therein.

period of time, a suitable door or like closure is opened and the drum applied to manually remove'the dusted bag fromthe drum. This operation has required the services of ma-ny assistants and has utilized much time'and labor. w z Itis an object of the present invention to provide a bag dusting machine wherein the bags may be automatically discharged from the drum after thesam'e have been dusted without resorting to manual labor.

To this end the invention aims to provide a bag dusting machine wherein theba'gs are dusted and prevented from, escaping from the drum during its'rotation in onedirection, while a rotation of'the machine inan the cleansed bag, a

The invention more" specifically comprehends a dusting drum having a plurality of door openings, which are maintained closed upon the rotation of the drum in one direction atgiven times toprevent the discharge of thebag. The drum, however, when rotated in an opposite direction causes" the hinged trap doors to automatically open and permit the bags, to be dischargedthrough the door openings at a given point directly upon'a. receiveror the like.

,In'the accompanying drawings, I, have disclosed a single embodiment of the inventioinbut it will be understood thatthe same is susceptible of many changes without departing from the spirit of the appended claims. 5, V V

while'the front thereof is, likewise constructed" of foraniinat ed material in part, which will be la ter described Y A The outline of the-drum resembles va paddle wheel, having the forwardly project- When the drum has been rotated a sufficient from said pointed ends openwork material 8.

Figure 2 shows the wheehdischarging dusted bags;

Referring "now fmore particularly to the drawings, wherein like reference characters indicate corresponding parts," the numeral l designates asuitable drum, mounted upon the shaft 2 supported in bearings 3 for rotation' b'y means of the cooperating gears El and 5. The sidesof the drum are preferably composed'of 'op'enwork wire fabric, 6,

Figure 1. The peripheral .p'ortionfof the drum is provided with "screen members 8 extending' between thef'sides thereof, which screen members terminate short of the, outwardly extending points 7 to provide openings for a purposewhich willlater appear.

As has beenstated, thepe'riphery of the wheel is of a somewhat stepped"'fo1imation, havlng eight pointed'extensions, the radial walls f the extensionspreferably being ot a soli d construction composed o'fwood or other suitable material, while i as previously pointed out, the peripheral portions spaced are generally of the Disposed'within the drum area plurality of agitating bars 9 thesame extending be tween the sides of said drum and serving to pick up or agitate bags or like articles disposed within the "drum during its 'rota- -'tion.' Any desired number of agitators may -be used, and these agitators are preferably composed of a relatively fiatpi'ece of wood or similar materiall V It will be observed thatby spacing the openwork peripheral sideportions 8 from the extensions '9, anopening is provided adj a; cent each extension, audit is therefore neces sary to provide means for preventing the "dischargeof bags through said opening during the rotation ofthe wheel. "To this end there is pivotally connected to .the ,drum, a series of trap doors 10, 11,12,13, 14,15, 16

and 17, one trap door being'pivotallymounted adj acent eachextension 9. During theroj tation of the dusting machine in the direction' ofthe arrow, Figure 1,: iti wlll be observed'that thetrap doors occupy such 18 on the right hand side of the drum, are

either closed or closing during the rotation of this drum, which prevents the bags from being thrown through openings 7, while the doors 14, 15, 16 and 17 are opened. inasmuch as the action of the wheel does not tend to throw the bags through these openings, as the same has a tendency to move the bags inwardly on the left hand side of the drum toward the axis thereof. The bags, after being placed in the drum remain therein during its rotation until a thorough dusting, has been effected, and cannot escape as long as the drumis rotated inthe direction of the arrow in Figure 1.

It. will be appreciated that the, bags, by falling upon thedoors and being supported by the agitating bars 9 serve to assist in maintaining the doors on the lefthand side of the machine closed during the dusting operation of the drum, and said bags do not dischargethrough the door openings on the side of the machine, partly because of the centrifugal action of the bags, and the fact that when the doors open the bags are caused to fall to the lower portion of the drum.

Ithas heretofore been the practice in bag dusting machines to manually remove the bags from the machine after a cleaning thereof., This has required considerable labor, utilizing much time, and it has been recognized by those skilled in the art that it would bea markedadvance if-eflicient automatic means could be provided for discharging the cleansed bag. The present invention aims to provide means for automatically dischargingthe bags, and to accomplish this, it is only necessary to reverse the direction of rotation of the wheel 1, so'that said wheel moves. in the direction of the arrow shown in Figure 2. WVhen; the wheel is moved in this; direction, the agitators 9 elevate the bags, and when the wheel is in, a position wherein the door 1.6 occupies the location shoWnin Figure 2, the same drops a. given bag upon the door 15, and when this door slides around to the positionoccupied by the doorl i, the bag automatically. drops through the opening 7 into a suitablereceptacle or upon a collecting table. Of course any numberof bags may. bedischarged at the same time through the doorv opening controlledby the door. 14, and, it will be appreciated that by arranging the pivoted trap doors in this manner, the reverserotation of; the drumwill cause the bags to be automatically discharged. from the drum in an exceedingly rapid. manner. The bags are. of. course elevatedduring the rotation of the. drum by the agitators 9,.and these :bags are discharged in the. manner disclofied igure 2 by being A .tainer when the same isrotated deposited at proper times upon the open in a position as'shown in Figure 2, certain bagsare dropping from beneath the agitator 9 located partly adjacent the door 16, which bags fall upon the open door 15, and these bags then slide from said door when this door reaches the position occupied by the door 14 shown in Figure 2. The agitators continuously raise the bags during the rotation of the drum andserve to drop or discharge said bags upon the appropriate doors as they reach certain positions, and these bags are then discharged in a manner hereinbefore described. In rotating the wheel to effect a dusting-of the bags,- it is desirable that the speed of the drum be maintained relatively low, say 16 revolutions per minute, but I have discoveredthat it ispreferable when dispelling the bags-toxrotate. the drum at. a greater rate of speed, as thisiserves to more expeditiously discharge the cleansed bag. Any means, such .as. gearing orthe like, may be. employed for rotating the drum at. a speed greater inone direction thanthe speed'of the drumv'when moved in the opposite direction, and likewise independent sources of power may be used for, moving the drum in its different directions, if this is found desirable. I

Having thus described the invention, what I claimis:
